Firefox was the Web runtime that gave us the best Web developer tools… some built-in, and then the likes of Firebug. We are seeing more, newer tools coming out of Mozilla. David Dahl, Firefox engineer, is working on a fun new console heads up display: Create an interactive Console to help web developers understand everything Read the rest…

Working on mobile Web apps such as the Facebook app on webOS offers one huge advantage over standard desktop development. You can code to a single runtime (in our case, WebKit).

Ben and I are often touting the fact that we are about to see amazing Web applications as browsers support more and more of “HTML5” and the engines under the hood have become world class. The GWT team has developed something that truly shows off this engine in their port of Quake2 to GWT. Seeing Read the rest…

This is a fun one. The Open Video Sliding Puzzle takes a running video (from the public videos project) cuts it up, and builds a sliding puzzle on the fly. How does it work? Why Canvas and HTML5 video of course: < View plain text > javascript for (var i=0;i&lt;12;i++){ var Read the rest…

Malicious code that targets browsers has quite some history and it gets bizarre when you see just how easy it can be to crash a certain browser.

For some time now, Adobe has been working with platform vendors to include the Flash plug-in pre-loaded. We’ve seen this ages ago in Windows, and more recently with Adobe’s efforts in the Open Screen Project. Now, there’s news of something a little bit different.

AOP? that is for whiz kids and Enterprise Java folk (or Lisp hackers have been doing it for years and years). Jonny Tran thinks that every time you use CSS, you’re doing Aspect-Oriented Programming”.
